SPECIFICATION forming part Of Letters Patent N0. 534,566, dated February19, 1895.

' Application filed May 19, 1894. Serial No. 511.842- (No model.)

.To aZZ whom it may concern.-

Be it known that I, THOMAS MILLER, a citizen of the United States,residing at Jersey City, Hudson county, State of New Jersey, haveinvented certain new and useful Im: 'provements in Urns, of which thefollowing is a specification.

My present invention is an improvement upon the coffee, tea or waterurns shown in my prior United States Patents Nos. 477,261, 486,881, and488,320, and has for its principal object to provide for the safeemployment of a readily removable or renewable earthen.- ware crock orliquid holding vessel within the outer casing, while at the same timelessening the number of parts, reducing the cost of manufacture andassuring increased convenience in the use of urns embodying all the mostdesirable features of construction.

The invention will first be described and then will be defined in claimshereinafter set forth.

Reference is to be had to the accompanying drawings, forming part ofthis specification, and in which similar numerals indicate correspondingparts in the several views.

Figure 1, is a central vertical sectional elevation of my improved urn.Fig. 2, isa bottom plan View thereof, in horizontal section on the linew, an, in Fig. 1, and partly broken away. Fig. 3, is a detailperspective View of the crock clamp ring or collar and bolt and adjacentparts. Fig. 4, is a perspective view of the heat deflector. Fig. 5, is abottom partial perspective view of the gas burner used for heating theurn 5 and Fig. 6, is a detail vertical section showing a modification.

The outer casing or body of the urn comprises a central shell portion 1,a headpiece 2, and a base-piece 3 5 the parts, 2, 3, having rabbets orshoulders on or at which the ends of the shell rest. Suitable legs 4,preferably fixed to a removable ring 5, sustain the urn at proper heightfrom a table, shelf or other support 6. The crock or liquid holdingvessel 7, which is preferably made of earthenware, has an upperoutwardly projecting flange or rim 8, between which and a horizontalportion of the headpiece 2, a suitable packing 9, is or may be placed.

Beneath the crock flange 8, is located a ring or collar 10, whichconforms generally to the shape of the crock and has suitableprojections or lugs 11, one for each of the two-part clamp bolts 12, 13,which sustain the crock.-

within the casing. The lug 11, may be cast or formed on, or maybeattached to, the ring 10, in any manner, provided it makes an abutmentfor the top interiorly threaded nut portion 14, of the lower longer part13, of the bolt, while the upper shorter screw-threaded part 12, of thebolt which passes through an aperture of the lug 11 is engaged by thenut 14:, thereby clamping the crock rim 8, and binding the crock andheadpiece (with or without the packing 9) securely together. The upperend of the bolt part 12, is preferably split and bent down and solderedfast to the headpiece. I prefer to use a wrought iron ring or collar 10,and to produce the abutment lugs 11, thereon by slitting the collarupward from the lower edge and then bending outward the metal betweenthe slits. See Figs. 1 and 3, of the drawings.

I Whether the packing 9, be used or not, I provide a water seal or trapat the joint between the crock 7, and the casing headpiece 2. This isdone by forming a groove or gutter 15, in and around the top of thecrock and extending the metal of the headpiece downward at 16, withinsaid groove, thereby causing water of condensation which drips from theurn cover, 17, to collectin the groove and form the water seal, as shownin Fig. 1, of the drawings. 7

The heat deflector and guard 18, located below the crock 7, protects thecrock and its laterally ranging fluid outlet 19, from overheating bypreventing direct impact therewith of flame or high heat from the burnerbelow, thus promoting the even heating of the entire liquid contents ofthe crock, and in substantially the same manner set forth in my twofirst above named patents. The improvement in this part of my inventionconsists in dispensing with the separate clamps formerly used to sustainthe crock, and in using the main crock holding bolts to support thedeflector. I accomplish this by providing the deflector with three ormore laterally projecting lugs 20, having slotted or bored extremities,through which the lower threaded ends of theparts 13, of the crock boltspass, and

whereby when the nut 21, is tightened on the bolt below the lug 20, thelatter will be drawn upward tightly to and beneath a horizontal shoulderor portion of the basepiece 3, while at the same time clamping the shell1, of the casing securely between the end parts 2, 3, thereof.

To assemble the main parts of the urn,the uncovered headpiece 2, isinverted. The packing 9, if used, is then laid on the headpiece. Thecrock is then laid on the packing. The clamp ring or collar 10, is thenlaid on the crock rim or flange 8, with the bolt parts 12, projectingabove the collar lugs 11. The parts 13, of the bolts are then screwed at14, upon the bolt parts 12, and tightly to the lugs 11. After the liquidoutlet pipe 19, is adjusted to the crock, the casing shell l,is laid onthe headpiece 2. The basepiece 3, is then laid on the shell. Thedeflector is then adjusted with its lug openings admitting the bolt ends13, and the nuts 21, are then screwed onto the bolts and tightly to thedeflector lugs 20, to bind the parts together.

The deflector 18, may at any time be removed without disturbing thecrock 7, and to allow cleaning of interior surfaces exposed to the heatof the burner, by simply removing the bolt nuts 21, but to remove thecrock itself, the parts 13, of the clamp bolts will be unscrewed at 14,after the deflector is removed and the crock may then be lifted out ofthe casing, with the ring or collar 10, thus allowing a cracked orbroken crock to be readily replaced by a new one without impairing theusefulness or the neat finish of any other portion of the urn. Theoutlet pipe 19, must of course be readjusted when renewing the crock.

In my earlier patents, the metallic liquid vessel is sustained partlyfrom the casing headpiece by nuts of clamp bolts, which engage beneaththe out-turned head or flange of the vessel. While these nuts and boltsmay safely help sustain a metallic liquid vessel within the casing, itis obvious that said bolt nuts would make an insecure sole support foran earthenware crock by clamping effect beneath the brittle edge of itsflange 8. Hence the surrounding ring or collar 10, sustaining the crockall around its flange is preferable as it makes, in connection with theclamping action of the bolts 12, 13, on the casing and collar, aperfectly safe and reliable fastening and support for the crock from itstop flange alone. Furthermore, the clamping action of the bolts at orupon the joint between the casing headpiece and the crock, through themedium of the encircling collar 10, and by the aid of the water seal at15, 16, (and with or without the packing 9,) always effects a tightconnection of the crock and easing which prevents escape'of steam fromthe crock or its cover tnto the hot air space 22, between the crock andeasing, thereby avoiding disagreeable drip of condensed steam or fluidupon the table on which the crock rests; and also preventing inwardpassage of deleterious gases or products of combustion from said hot airspace to the interior of the crook, thereby preserving the purity of theliquid contents of the crock.

The comparatively short parts 12, of the clamp bolts are expanded solittle by the heat rising from the burner, that the joint between thecrock and headpiece 2, is not loosened, and the expansion of the largerparts 13 of the bolts accommodates the expansion of the casing whilepermitting said parts 13, to always give ample support to the deflector18, below the crock. In this preferred construction the crock 7, issustained solely from its upper flange, aided a little by the pipeoutlet 19. Hence the crock is free to expand or contract more or lessthan the metallic portions of the urn, thus promoting durability of theentire structure.

In the modification shown in Fig. 6, of the drawings, the deflector 18,is not used and suitable clamps 23, through which the bolts 13 pass, areinterposed between the bottom of the crock and the basepiece of thecasing.

The flame head2-1t, of the burner, is passed upward through thepreferably rounded opening 25, of a bottom guard plate 26, held withinthe basepiece 3, by the leg frame 4, 5, or otherwise. This plate 26,prevents downward escape of heat and by its opening 25, admits propervolume of atmospheric air past the burner flame which heats the airprior to its rising through the space 22, for heating the crock of theurn. I now provide the plate 26, as its air inlet opening 25, with ametal frame or guide 27, preferably made rectangular and of proper sizeto admit and retain within it the head of the burner and cause thelatter to always be centered relatively to the opening 25, to assureinward passage of the air in even volume all around the burner head forevenly heating all the air admitted at the opening 25, prior to itspassage upward to the urn hot air space. This plate 26, is preferablyheld up to stops on the casing basepiece 3, by downward extensions oftwo or more of the clamp bolt parts 13, which receive extra nuts belowthe plate, as shown in Fig. 1, of the drawings. The waste hot productspass slowly from the space 22, through upper apertures 28 made in theshell 1, of the casing.

The burner has a wire gauze inlet at 29, for atmospheric air whichcominingles with gas admitted from a pipe 30, leading from anyconvenient source of supply. I" make the burner with an arched or hollowbase 31,

above which a lateral gas inlet is provided at 32, to receive a nippletaking gas from the flexible tube 30, attached above the table 6, and asshown in full lines in Fig. 1, of the drawings. I also provide theburner stem with a bottom opening 33, adapted for attach ment of a gassupply pipe coming through the table from below. An interchangeable plug34, shown closing the opening 33, is adapted also to the other opening32, thus perat the lower opening 33. The urn has the usual fluid gage35, communicating with the fluid outlet 19, and the faucet 36, as shownin Fig. 1, of the drawings.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination, with'the casing and the crock orliquid vessel, of a detachable ring or collar on the crock, and clampingdevices engaging the casing and collar, substantially as described. 7

2. The combination, with the casing, the crock or liquid vessel, and adetachable ring or collar on the crock, of two-part bolts drawing uponthe casing and engaging the collar, substantially as described.
